All vests come with one included cartridge, but we recommend you always carry a spare. If you buy spares with the purchase of your vest, then there is no added shipping cost. Cartridges are considered hazardous material and must ship ground.

Cartridges or canisters will last indefinitely but should be replaced with the first sign of rust or surface deterioration.

Each jacket comes with a handy Tool Kit (also available as optional accessory) to complete the replacement quickly and easily.
